DAST-promoted Beckmann rearrangement/intramolecular cyclization of acyclic ketoximes: access to 2-oxazolines, benzimidazoles and benzoxazoles.

The first example of DAST-promoted Beckmann rearrangement/intramolecular cyclization of acyclic ketoximes is described. This unique protocol represents a direct and effective pathway to 2-oxazolines, benzimidazoles and benzoxazoles in moderate to good yields.

Hot water-promoted cyclopropylcarbinyl rearrangement facilitates construction of homoallylic alcohols.

In refluxing 9 : 1 (v/v) H2O-1,4-dioxane and without an additional catalyst, the rearrangements of various types of cyclopropyl carbinols were attempted. It was found that the reactions generally gave homoallylic alcohols in good to very high chemical yields. Rearrangements of bicyclic or tricyclic cyclopropyl carbinols readily gave the desired ring-expanded cyclic homoallylic alcohols which ar...

Synthesis and Silica Gel Promoted Rearrangement of 5-Methylthio-3-carbo-r-butoxy-pent-3-en-2-one

Since the discovery by Knoevenagel [1] that doubly activated carbonic acids (CH-acids) react with carbonyl compounds to give the corresponding conjugated olefins, this reaction has been widely used in organic synthesis as an important method for carbon —carbon bond formation [2, 3). The conden­ sation of 1,3-dicarbonyl compounds with monocar­ bonyl compounds usually leads to a,/3-unsaturated pr...
